FOREPART-TURNING MACHINE.

Application led April 9,

Turning Machines, ofwhich the following is a specification, reference being had thereyin to the accompanying drawings. n

This invention relates to machines for turning the foreparts ofshoes'bcing of the general type disclosed in the patent to Eppler, #706,038 August 5, 1902, in` which a lforni .is provided` toreceive the shoe, the 'heelof whichV has been previously turned, and cooperating turning elements are provided by means of which the sole 'is so ma- ;nipulated on' the form as to enable the operator to peel' the shoe `off the form by hand, and over one' of the elements right side out.` I n This invention provides various adjust- I-,ments for renderingithe machine more con- ,venient to the operator and more satisfactory in operation with various grades and styles of shoes.

1t also provides an improved form for supporting the upturned shoe and a cooperating turning implement therefor by ,which the sole may be properly broken to facilitate the turning operation.

These and other objects `and advantageous details of construction and arrangement of parts will be apparent from a more comlplete description of one embodiment lof .the invention disclosed in the accompanying drawings in whichfl Fig. 1 is a side elevation of the machine ;l

1919. Serial No. 258,706.

The machine base A, of any suitable description, has carried thereon a vertically adjustable head B. `Head B carries a base C in the form of a substantially T-section rod. At one end the base C is upwardly turned as at 1, and has pivoted thereon at 2 a sleeve member 3 provided with an in-v wardly extending abutment 4. A rod 5 is clamped at one end in sleeve member 3 by means of clamping bolt 6. Rod 5 extends parallel to base C and at its other end passes througha sleeve 7 A sleeve 8, provided at one end with a" clutch face 9, is rotatably mounted on rod 5 and carries at opposite lateral sides bosses 10, 10a on which is pivoted, by means of bolt 11, a yoke member 12 having an upwardlv extending arm 13 and a horizontal arm 14 integral therewith. A sleeve 58, provided with a mating clutch face 59, is carried by rod 5 and is adjustably secured thereto by a set screw 60. Arm 14 carries a depending `link 15 which may be attached by a chain 16 or other suitable means, to a treadle 17 pivoted at 18 in the base A.

Sleeve 8 carries a bracket member 19 integral therewith and extending upwardly. It

also carries a depending abutment member 20 provided with aset yscrew 21 adapted tol Contact with abutment 4 at certain times. At its upper end bracket 19 is provided with a socket to receive one end of a turning implement 22 suitably fastened therein by a setscrew 23. Pivoted to bracket 19 at 19 is a'body abutment 24 in the form of a depending plate with a curved top portion. Member 24 is" provided with a bracket through lwhich the pivot 19 passes, and which is further provided with a curved slot 26 through, which a bolt 27, screwed into bracket 19, may 'pass Sleeved on turning implement 22 is a slide 28 having a slot 29 in the top face thereof in which a roll 30, mounted on pin 31 fast in implement 22` may play to allow member 28 to slide lengthwise of implement 22 while preventing rotation thereon. A link 13DL is pivoted at one end to the arm 13, and at its other end to sleeve 28.

The other end of implement 30a is y; spring 66.

35 at its upper end. Between lever 34 and` the end 53 is placed a compression coil spring`36 which urges roll 35 upwardly.`

Roll 35 cooperates with a cam member 3 7, having-atang 38 projecting within a suitable opening in bracket 19, and made fast therein by a set screw 39.

At its opposite end base C is forked as shown at 40, 40, and between the forks is p-ivoted a sleeve 41 on a pivot 42. Sleeve 41 has a depending-sleeve 43,.-preferably inte'gral therewith, through which Ais adapted to slidea rod 44 lwhose upper end enters the lower end of a boss `45.*pivoted` at 46 between jaws .47, 47EL integral with sleeve 7.

A set screw operated by hand wheel 43 serves to retain rod 44m any. desired position.

Also preferably integral with sleeve 7 are two pairs of upstanding guide members 48,

48a; 49, .49ar slidably carrying therebetween a plunger 50. i An adjusting screwl passes own through a suitable portion of plunger 50 and engages at its lowerend the Ired 5.

Atits top, plunger() isprovidedlwith a circular platev 51L4 and centrally pivoted.

thereon, by means of a pin 52, is a turret memher having afseiies of substantially radiallarmsl54, which may receive projecting ytangs of suitable forms `such as 55, which vvIriay be made fast therein as by set screws form `may `b eiprovided with longitudinal corrugations as 57 on its upper lconvex surface, asl shown in Figs. 9 and 10.

Passing up through a suitable opening in plate 51a is a latch member 61 adaptedy to..

engage in any one of a plurality of openings 62, in the lower Jitace of turret 53 to retain any desired one of the` forms 55 in sub stantialalignment with turning implement 22. Latcli61 may be retracted to release the turret whenever desired by means oli' a link 63, connected to one arm of a bell crank 64,` having a handle en` its opposite arni, andl which is normally urged into a position to lock the turret by means of a The operation of the `machine is. asfollows: including turning implements 22 and 30, is rocked to one side, as shown by dotted linesin Fig. 2. The limits ofrocking motion,` which may b'e imjzai'tedw to the sleeve,

rmay be adjustably determined bythe settings of sleevef-S- andset serew'21. shoe, the heel of-.why-ich has been turned, isfthen placed over the forni 55,'the spoon-shaped The mechanism car-riedby sleeve 8,

portionexjtending into thei'orepart. The turning implement 22 `is `then rocked upwardly into alignment with form 55 and the operator thenA depressestreadle 17. This serves to slide member28 toward the form, and roll732 engaging the sole of the shoe thereon presses it upward into substantially the contour of the underside of the form, 4thus breakingthe sole so that the turning operation is facilitated. The operator then grasps the sli-oe neargthe heel and braces liiins'elfagainst the body abutment 24, and pulling towards him, peels` the slioerfroni the form in its turned condition and over onto the turning implement 22, at the same time allowing the auxiliary Aturning imple nient 30FL to retract out of the way.

During the i turning t operation fthe press ing of the seleupwardly A i1-ite thev eoneavity ot `the form serves to strain the` upper over the convex sur-face of the fer-1n, whereby4 it is kept in proper position for turning Without necessitating the employmentiof an aux.- iliary tool or device f orkeepingtlie upper inssinooth condition during the operation. The flat marginal portion of the lower face of the forni causes the sole-to be held substantially fiat longitudinally, thev breaking thereof lpreliminary to the turning,operation being transverse, thus insuring i an easier breaking action than if it were attempted to break the sole both longitudinally and laterally, and at the; Sametime avoiding longitudinal distortion owthe. upper. The corrugations; on the formi shown in.` Figs. 9 and 10` serve to decrease the contact' area of the upper on the -iogrnifandf` make more easy t-he peeling of thetshoe therefrom. The turning operation ywith this mechanism leaves the sole ',Glowned or bulged outwardly at the end oi the drawingoperation so that it isin condition for, reflasting without further manipulation to-eflectthe crowning, as has heretofore been-found necessary. i

For the purpose of adapting the machine to the requirements of theindividual opera.tor;an ddiferent grades andstylesof shoes the following adjustments may heeffected. By loosening the` hand: wheel; 43 and the `proper set screws, rod 44 vmay be pushedy upT wardly, thus raising the endof-red 5. about theA pivot point 2, lthuschanging the?4 angle of the turning implement 22 and the form 57 te thehoriaontal., At the sametimethe body abutment 24niay. bei'adjustedZ to substantally vertical position by` means of` the slot 26 and bolt; 27,50 as tube-comfortable for theV operator; Sleeve-.V71 maya-also. be adv' j usted longitudinally of rod 5 to adjust the distance between theends? oimplement 22 and form 57 in order toaccominodateadif-J ferent ihfkneee O stock` Iand :diierent styles of, Shoes-asmay be:recjwired.J The tur let 53 may also? be adjusted-:vertically with iso Y CII able independent' of the other parts `vertically and towardV and away from the turn` ing implement. The limits of the swing of the turningimplementabout rod lare adjustable lin both directions. It is thus clear thatA the operator may adjust the machine to the most comfortable-angles and positions l for his individual.requirements and also for different types of shoes to be operated upon.
